Moves C index to 2 on the D scale Moves indicating line to 2 on the C scale Reads 4 on the D scale
Good thing 2+2 and 2*2 yield the same answer. Would have to bust out the addiator otherwise

Zerush@lemmy.ml 1 day agoYou can’t calculate 2+2 with a slide rule

abacus say what?
Yoy can use 2 normal rules to add/rest 2 numbers, but you can’t do it in a slide rule with its logarithm scales.
Well, but fails with 3+3, there an US engineer must use still an addiator. Nowadays it’s easier with an pocket calculator.
Maybe you can’t

You could probably do log_10(10²×10²) instead?

It’s the same as 2*2
